A stack is a linear data structure that follows the last-in, first-out (LIFO) principle. Elements are inserted and removed from one end called the top. The basic operations are push, which inserts an element at the top, and pop, which removes the top element. Stacks have many real-world applications like piles of books and evaluating mathematical expressions. An array can be used to implement a stack by storing elements from index 0 to the top index, and incrementing or decrementing the top index during push and pop operations.

OpenStack Glance provides image discovery, registration, and retrieval services. It has a RESTful API and supports storing images on various backends like filesystems and OpenStack Swift. Glance components include the Glance API, registry, and database. It supports many disk and container formats and has a caching mechanism. Images can be managed through the Glance API and used to launch instances.
Glance is OpenStack's image service that stores and retrieves virtual machine (VM) images and their metadata. Glance consists of several components - the glance-api service that handles image API requests, the glance-registry service that stores and processes image metadata, and an image store like OpenStack Object Storage where the actual image files are stored. Glance supports various image formats like QCOW2, VHD, VMDK etc. that can be used by different hypervisors. Images in Glance can be public, private or shared between specific tenants using image members.

This document discusses 5G and multi-access edge computing (MEC). The key points are: 1) 5G can achieve latency of 100ms while 4G is 300ms, and 5G bandwidth is 20Gbps compared to 4G's 1.29Gbps; 2) MEC deployed close to users on 5G can achieve even lower latency of under 10ms; 3) MEC integrated with 5G can enable new applications for IoT, VR/AR with high speed and low latency.

Here are the key points from the AT&T presentation on their "Network AI" framework:
- AT&T is developing an open source framework called "Network AI" to drive their software-defined network transformation.
- The goal is to apply AI/machine learning techniques to continuously optimize their network performance. This will be done by collecting massive amounts of network data and using it to train ML models.
- As part of this effort, AT&T is contributing several open source projects to the Linux Foundation like Airship, Akraino, and Acumos. Airship provides tools for deploying OpenStack and Kubernetes on the edge, while Akraino is an edge computing framework. Acumos allows for developing and
